SPECIFICATION forming part of Letters Patent No. 512,916, dated January16, 1894.

Application filed May 2, 1893. Serial No, 472,735. (No model.)

To aZZ whom it may concern:

Be it known that I, ARTHUR STABLES, of Mannborough, in the county ofAmelia and State of Virginia, have invented a new and Improved SlidingPlaner, of which the following is a full, clear, and exact description.

The invention relates to wood working machinery, and its object is toprovide a new and improved sliding planer, which is simple IO anddurable in construction, very effective in operation, and arranged toplane a perfectly smooth and true surface.

The invention consists of a reciprocating cutter head, and a feeding andclamping de- I 5 vice of especial construction and serving to 01631 thework and feed it over the said cutter The invention also consists ofcertain parts and details and combinations of the same, as will be fullydescribed hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar letters of reference indicate 2 5corresponding parts in all the figures.

Figure 1 is a plan view of the improvement. Fig. 2 is asectional sideelevation of the same on the line 22 of Fig. 1. Fig. 3 is a transversesection of the same on the line 33 of 0 Fig. 2. Fig. 4is a sectionalside elevation of one of the slides for the cutter head; and Fig. 5 is aside elevation of the cutter head.

The improved sliding planer is provided with a suitably constructedframe A, support- 3 5 ing on its top a table 13, formed with an openingB, in which reciprocates the cutter head 0, carrying a knife D, adaptedto engage the under side of the work, to plane the same, as hereinaftermore fully described. The cut- 0 terhead O is provided at its front andrear sides with inclined lugs C, see Fig. 5, fitted to slide incorrespondingly shaped grooves E formed in slides E, mounted toreciprocate on guideways F, secured to the sides of the main On theunder side of the cutter head 0 are formed lugs 0 pivotally connectedwith a pitman G, connected with a crank disk H, held on the main drivingshaft I, mounted to turn in suitable bearings in the frameAand providedwith fixed and loose pulleys I, connected by a belt with suitablemachinery to impart a rotary motion to the said shaft I, so that thecrank disk H and the pitman G reciprocate the cutter head 0, travelingwith its slides E on the guideways F.

It will be seen that on the forward stroke of the pitman G the lugs G ofthe cutter head 0 first slide forward in the recesses E until they cometo the ends thereof, after which the further forward movement of thepitman causes the slide E to travel in the guideways F. By this forwardmovement of the cutter head 0 in the slides E, the cutting edge of theknife D is brought in contact with the under surface of the work Jsupported on top of the table between the sets of rollers K, K and K Kand when the pitman G is on the return stroke, the cutter head 0 travelsdownward a short distance in its slides E, so that the cutting edge ofthe knife is moved out of contact with the under side of the work J.

The sets of rollers K, K and K K are journaled in suitable bearingsformed in the side frames L of a frame L extending horizontally belowthe pitman G, and the cutter head 0 as plainly shown in'Figs. 2 and 3.The rollers K and K are journaled in stationary bearings, while springsN, N press on the bearings for the rollers K and K respectively, so thatthe work J is firmly held between the sets of rollers.

The frame L is formed in its middle with a socket L mounted to turn on aboss 0 forming a bearing for the upper end of a shaft 1? disposedvertically and journaled in suitable bearings in the main frame A. -Onthis shaft P is secured a pulley P over which pass the belts Q and Qextending diagonally in opposite directions, as is plainly shown in Fig.1, the said belts passing over idlers Q Q respectively, up and overpulleys Q and Q respectively secured on the shafts of the rollers K andK respectively, so that when the shaft P is rotated a rotary motion istransmitted by the pulley P, the belts Q and Q and pulleys Q Q to thetop spring-pressed rollers K and K By this arrangement the work J is fedforward in the roller frame on top of thetable B, so that at each strokeof the cutter head 0 the knife D comes in contact with a new surface tobe planed.

In order to impart a rotary motion to the shaft P from the main drivingshaft I, the following device is provided: On the lower end of the shaftP is secured a disk R, in frictional contact at its under side with afriction pulley R mounted to slide 011 and to turn with a shaft Rextending transversely and journaled in suitable hearings in the frameA. A shifting device S is connected with the pulley R to move the latteron the shaft R nearer to or farther from the center of the disk B, so asto increase or decrease the speed of the said disk R and the shaft P toobtain more or less feed for the rollers K and K at one revolution ofthe shaft R The latter carries a pulley R connected by a belt R with apulley R secured on the main driving shaft I, so that when the latter isset in motion a continuous rotary motion is transmitted to the shaft Rwhich, by it friction roller R, rotates the disk B, so as to impart arotary motion to the feed rollers K and K It will be seen that when theWork J is arranged between the sets of rollers K, K and K K and the maindriving shaft I is revolved, then the work J is fed forward, and at thesame time the reciprocating cutter head 0, by its knife D, makes a cutin the underside of the work J on each forward stroke. On the returnstroke of the cutter head C it moves downward slightly, as beforedescribed, so as to move the cutting edge of the knife D out of contactwith the under surface of the work J during the return stroke. By thisarrangement the cutting edge of the knife D is not liable to be dulled,and a clean, perfect cut is made at all times.

It will further be seen that no additional strains whatever are exertedon the cutter head 0, so that the machine can be run with comparativelylittle power.

IIavin g thus fully described my invention,

I claim as new and desire to secure by Letters Patent- 1. Aslidingplaner comprising a reciprocating cutter head provided with inclinedlugs, slides formed with angular recesses engaged by the said lugs, andmeans, substantially as shown and described, for imparting a forward andbackward movement to the said cutter head, as set forth.

2. A sliding planer provided with a cutter head having inclined lugs andreciprocating slides formed with angular recesses engaged by the saidlugs, substantially as shown and described.

3. A sliding planer provided with a feeding device for the work,comprising two sets of rollers, side frames in which the said rollersare journaled, a main frame carrying the said side frames and mounted toturn, a shaft forming the center for the said frame, a pulley on thesaid shaft, and belts connecting the said pulley with pulleys on theuppermost feed rollers, substantially as shown and described.

4. A sliding planer provided with a feeding device for the work,comprising two sets of rollers, side frames in which the said rollersare jonrnaled, a main frame carrying the said side frames and mounted toturn, a shaft forming the center for the said frame, a pulley on thesaid shaft, belts connecting the said pulley with pulleys on theuppermost feed rollers, a disk held on the said shaft, and an adjustablefriction roller engaging the face of the said disk to impart a rotarymotion to the latter, substantially as shown and described.
